Could you show me which part is the relay that I should replace in the picture below? Or could you show me where to get the relay diagram? It would be great if I could get it repaired on my own. I don't want to pay for the service because my car has just been 12,km, a year and a half.Honda designs and manufactures a wide range of vehicles.
Many of Honda's vehicles are equipped with air conditioner units. The AC compressor clutch is the power feed to your AC compressor. The compressor is the unit that cools the air before it enters into the Honda's cabin. If your AC is not properly cooling the vehicle, the AC clutch relay could be faulty.
You can test the clutch relay for power with a test light. Turn the Honda engine on.
Anyone have a/c problems with Honda Civic?
Turn the AC settings to "Off. Locate the AC clutch relay. Trace the wire that runs off the AC compressor; this wire plugs into the clutch relay. The relay is mounted on the firewall. You will notice a three-wire connection on the relay. Connect the test light clip to the negative battery terminal.
Touch the test light lead to the middle of the three wires. The middle wire receives power from the clutch relay. The wire should read "Inactive.
Turn the AC control to "On. Touch the test light lead to the middle wire once more. The wire should now read "Hot.

Kings Mills, OH Any suggestions would be greatly appreciated. Next is to check static pressure. You need a gauge to connect to the low side connector the smaller blue some are not colored capped one.
Pressure in the system if it is reasonably full with compressor disengaged should be about psi. No problem, let us know what the pressure is and we can go from there. If the Freon has leaked out that could explain your no engagement as the system has pressure sensors to prevent the compressor from engaging if the Freon level is too low. Ok, so I finally got a set of manifold gauges. I just want to verify that my ideas are correct.
Here is what I planned on doing:. Close all the valves on the manifold gauges. Attach the blue hose to the low side. Open the low side valve on the manifold gauge.
Read the pressure. You are missing the ambient temperature. Opening the low side valve on the manifold will connect the low side hose to the service hose. Close both valves on the manifold. Connect the low side hose to the fitting on the car. If your hose has a knob at the connection, turn that to engage the hose with the low side fitting.
That should be all you need to do. At that point, you should have a reading on your low side gauge. Once you are satisfied with your reading, loosen the knob on the low side fitting not on the manifold, on the fitting and then remove the fitting from the low side service port.
Be sure to reinstall the protective cap on the service port. I thought thats what he meant the knob for the gauge hook up that hooks to the car service port? Unless i miss read his post i didnt know he was talking about the gauge manifold.
I read it the other way about.After reading a lot there are some possibilities: 1- Open ground at the chassis 2- Under Dash fuse box multiplexer bad 3- 4- Please help My car has an automatic transmission.
Hi there. The air conditioning clutch could be not working for the refrigerant could be low or the clutch could be burned up. If there is a voltage present then the clutch is burned up and needs replaced. If there is no voltage present, then the system could be low on refrigerant or the low or high side pressure sensor has failed. If there is voltage to the sensors and nothing past the sensors, then the system is low on refrigerant.
The cooling fans and condenser fans either are not coming on from a loss of power or the motors are burned up. First check the cooling fan circuit. If there is no power to the cooling fan, then check the fuses and see if they are burned. If the sensor has power to it an after, then the switch is working.
If there is power to the motors on the cooling fan, then the fan motor is burned up and needs replaced. For the condenser fan, if there is no power to the fan, then check the fuses for any of them burned. If there is power to the motor, then the condenser fan motor is burned up and will need to be replaced. For the ceiling light courtesy light is not working when the door is open, then there could be an issue with the bulb being burned or the switches are damaged. First check to see if the light is just turned off.
If the light is on the door settings, then check the doors one at a time and see if the door courtesy light switch is broken, stuck, or has a loose or corroded ground.
If the ground is good and there is no problems with the switch wiring, then I recommend replacing the door courtesy light switch. For the parking brake light always on, check to see if the parking brake lever is all the way down in the unlock position.

It does start working again after you drive for a while. The first one it took us several attempts taking it to the dealers before they could figure out what was wrong with it. They then found it was a resistor. Now we are having a problem with the other Honda Civic, same problem Looking around online I find that there are others having this problem and that it has gone back for a few years. I wonder if this is a defect the Honda corporation knows about but it continuing to produce cars with it since it seems to only happen in warm climate areas??
Also, the dealership NEVER got a code with this problem on the first car, it was only through testing that they said it was the resistor! I have a Honda Civic that is suffering the same problem. Today, I kept cycling the temperature control knob from cold to warm and back.
How to Know If the AC Clutch Relay Is Bad on a Honda
I feel that there is a short, or possible a bad resistor in the temp control. I have checked the freon level and it is full. Has to be electrical. I have a Honda civic. My problem started at 85k first with a clutch relay switch problem.
The 3 months later it went out and then they said they had to put a software patch on the clutch relay switch. That lasted like 6 weeks, then the compressor finally went out and I filed a complaint with Honda of America.
Honda corporate refused to acknowledge other Hondas with similar issues, said ac issues didn't have critical issues etc After replacing my ac compressor with my private mechanic since Honda dealers wouldn't take responsibility for the ac compressor going out at 92k, my ac is not working again after The ac they use in these Hondas just seems to be defective and Honda will not do anything about it or acknowledge it.

I have a Honda and one day I went to go start it and everything and the car wouldn't start nor would the hood open to jump start the car. So they just unplugged it and it works. I have a Honda Civic. The air conditioner randomly quits working from time to time.
It only takes a minute to sign up. I have a Honda Civic LX with about 70k miles on it. As of a few weeks ago the AC really started having cooling problems; however, this all seemed to happen gradually.
It seems to get a bit colder if the engine is revved but at idle on max AC you can barely tell that it's on. This does not seem normal for a four year old car. After some research I did see people having similar problems but none as specific as mine. I am not sure where else to start looking. Let me know if more info is needed. Any help would be greatly appreciated.
They told me there was an issue with the compressor clutch so they ended up replacing both the clutch and compressor all together. I tried to get them to warranty the work at the time with no luck. AFTER 2. It seem to go out in a similar way as it did last time.
It would be cold for the first mins of the drive then hot. This time the compressor clutch doesn't engage and condenser fan does not come on.
After taking it to my mechanic and watching him diagnose it, we are leaning towards the the compressor being shot. When he put power directly to the clutch bypassing the AC relay which was the first thing I replaced with no luck you could see and hear the engine struggle as power was applied and eventually caused it to stall the car. This might be a different issue then the previous issue where it seems instead of it being the compressor clutch it looks like the compressor itself has seized.
Really disappointed in Honda after all this. Overcharging the system will damage the compressor. My brother had the same problem with he's Nissan sunny versa all those you mentioned is been done until I found out that the Temperature selector cable is loose so this means its stocked and its no longer select from heating or cooling so maybe yours is on heating still because the cable is loose it wont go back to cooling, it doesn't matter what's the Temperature selector showing from outside because the cable is loose and always mixing cold and heat at the same time, so see if your is not loose for the sunny air conditioning unit was manual I am not sure if your Auto maybe its differentI hope this helps.
I can't find the reason tjis worked??? Those honda civic tend to leave the heat on of the heat system the valve tends to stay a little open and the heat will mix with the cold of the compressor, you just have to disconect the heat systems fuse and manually close the valve that is located behind the radio.

Asked 5 years, 2 months ago. Active 2 years, 3 months ago. Viewed 23k times. Things I know: I can see the compressor engaging with no hesitation and staying on. The blower fan seems to be normal, putting out the usual amount of air. The condenser fan turns on. If I touch the low pressure AC tubing it seems very cold. It doesn't seem to matter how long the AC is running it usually stays the same temperature unless the RPM increases.
Things I have tried: I have checked the pressure of the refrigerant on the low tubing and it seemed normal. I added a few psi of freon out of desperation with no change.Diamond Jim helped make these videos. We are still working to obtain content for your car, however the video above is believed to have similar characteristics as your car. When the air conditioner in your Honda Civic starts blowing hot air, you likely have a freon leak.
Most refrigerants include a leak sealer that will seal small leaks in addition to filling the Ra refrigerant. If there is a problem with your compressor or evaporator, adding freon will not restore cooling.
Which is the A/C Clutch Relay?
How to add freon to your Honda Civic: hook up the can of refrigerant likely ra to the low pressure port. When your compressor kicks on, add freon to the correct pressure.
In addition to cooling, freon lubricates the compressor when it runs. Burnt out brake lights increase your chance of getting rear ended - check and change yours today.
